After giving birth to her third child in March 2019, Jessica Simpson lost 100 pounds by incorporating healthy, sustainable habits into her lifestyle rather than doing anything too drastic.

This meant walking 14,000 steps a day, focusing on eating lean proteins and vegetables, and prioritizing sleep, her long-time trainer Harley Pasternak told E! News.

“It had to be more than just getting back from her baby weight, but how do I keep whatever I am doing now forever,” Pasternak said. “That’s why we are not a big fan of doing any extreme diet or radical forms of exercise.”
